BOTTLE Filed March 26, 1930 Patented Jan. 19, 1932 UNITED STATES PATENT OFFICE ADOLIE PLATTRING, OF BERLIN, GERMANY, ASSIGNOR TO THE FIRM STERN- VERSCHLUSSE G. M. B. H., 01 BERLIN, GERMANY BOTTLE Application filed March 26', 1930, Serial No. 439,095, and in Germany April 11, 1929.

This invention relates to a bottle having an opening in the neck thereof for the formation of drops of liquid poured from the bottle through the opening which serves at the same 5 time to admit air to the bottle.

According to the principal feature of the invention a conduit leading from the drop forming edge of the said opening in the neck of the bottle, is provided in the glass of the latter. This conduit is not of advantage only because it ensures that the drops of liquid shall leave the bottle always at the same place, but also because unless the opening bears a certain relation to the viscosity of the liquid contained in the bottle, drops will not be permitted to leave the bottle at all, should such a conduit not be provided in connection with the opening formed in the glass of the bottle. If the conduit is not provided, the liquid contained inside the bottle will probably form simultaneously a skin over the drop opening of the bottle thus closing the latter and preventing the entrance of air and therefore also the exit of liquid. When the conduit is provided, however, no skin is formed, and the liquid can therefore be poured out drop by drop without hindrance.

I am aware that it is known to arrange drop conduits adjacent to the drop openings of bottles in such cases where a special opening is provided for admitting air to the interior of the bottle. In this case, however, the drops will leave the bottle also when no conduit is arranged adjacent said drop opening, and said conduit therefore is of no value for allowing the liquid to leave the bottle.

The invention will now be described, by way of example only, with reference to the accompanying drawings in which Figure 1 is a side elevational view of the improved bottle with the neck of the bottle shown in section, Figure 2 being a corresponding plan view.

Figure 3 illustrates in side elevation a modification.

Figure 4 illustrates in side elevation and partly in section a further modification, Figure 5 being a corresponding plan View.

Referring first to Figures 1 and 2, the neck 2 of the bottle 1 is provided with a glass external screw-thread 3, and the mouth of the bottle has a tapered closure seat portion or lip 4 extending perpendicularly with respect to the axis of the neck, so that the bottle may the air to the bottle, is located eccentrically,

i. e., to one side of the axis of the neck 2. The opening 6 is, in the embodiment of the invention illustrated in Figures 1 and '2, triangular and one angle 7 of the triangular opening is located so that it is directed clownwards when the bottle is tilted in order to obtain drops of liquid therefrom, i. e., directed towards the axis of the bottle. A groove or recess 8 is provided in the outer or upper surface of the wall 5, this groove or recess being in communication with the triangular aperture 6 at the angle 7 thereof and serving for allowing drops to leave the bottle and for conducting the drops out of the bottle. As shown in Figures 1 and 2 the recess or groove is triangular but in its place one or more simple grooves with parallel boundary walls could be provided or even one or more ribs.

The embodiment of the invention illustrated in Figure 3 differs from that illustrated in Figure 1 in that a groove or recess 14 is provided in the screw-thread 11, a rib 13 being provided on the outside of the neck of the bottle 10 below the groove or recess 14 and in alignment with it. In this embodiment of the invention, the liquid, which proceeds from the opening 6 into the groove or recess 8 in the outer surface of the transverse wall 5 and is conducted to the seat portion or lip 12 of the bottle, flows over the latter into the groove or recess 14 and along the rib 13, so that the division into drops of the liquid poured from the bottle is facilitated.

Instead of the groove or recess 8, a corresponding rib may be provided in all embodiments of the invention and on the other hand the rib 13 may be replaced by :1 corresponding groove or recess.

The opening in the transverse wall may have another form, construction and arrangement than that illustrated in Figures 1 and 2 of the drawings; for example, it may be polygonal or circular and it may be arranged centrally with respect to the axis of the neck of the bottle.

Referring now to Figures 4 and 5, it will be observed that here again a relatively thin transverse wall 16 is provided, the lower surface of which is plane and perpendicular to the axis of the bottle, whilst its upper surface is concave. In the transverse wall 16 is a central opening 17 and tangential to this aperture a groove or recess 18 leading to the outer edge of the wall 16, the groove or recess 18 being adapted to allow the entrance of air through the opening 17 and the exit of liquid drops and to conduct liquid from the apertune 17 to the transverse seat portion or lip of the neck of the bottle at two opposite points therein.

The segment 19 of the transverse wall 16 adjacent the groove or recess 18 may be slightly thickened as shown in the Figure 4, so that, when upon pouring liquid from the bottle the latter is tilted not only towards the one end of the groove or recess 18, but also towards the thickened segment 19, the internal wall 20 of this thickness 19 serves to retain the liquid coming out of the aperture 17 and conducts it to the lip of the neck of the bottle. Thus the stream of liquid coming out of the opening 17, is flattened and spread, so that the simultaneous entrance of the air through the opening 17 is facilitated. It will be evident that such an arrangement may also be contemplated when employing another form of opening 17, located in another position, as, for example, when employing a triangular or polygonal opening located eccentrically or otherwise with respect to the axis of the neck. In this case also, one or more grooves or recesses may be provided in the outer surface of the neck of the bottle, in order to facilitate the separation of drops, these grooves or recesses being preferably in the same Plane as the groove or recess 18.

Instead of a screw-cap closure, a stopper closure may be employed, the transverse wall in the neck being located at a suitable distance from the mouth of the neck of the bottle, and the inner part of the neck being so formed, that a cork or glass stopper may bfiinserted above the transverse walls with out coming into contact with the latter.

Having now particularly described and ascertained the nature of my said invention, I declare that what I claim is 1. A bottle having a restricted opening in the neck thereof for the formation into drops of liquid poured from the bottle through the restricted opening which serves at the same time to admit air to the bottle, a conduit leading from drop-forming edge of the said restricted opening in the neck of the bottle, said conduit being provided in the glass of the latter.

2. A bottle having a restricted opening in the neck thereof for the formation into drops of liquid poured from the bottle through the restricted opening which serves at the same time to admit air to the bottle, said restricted opening being angular at that side turned downwards when dropping liquid from the bottle, a conduit leading from drop-forming edge of the said restricted opening in the neck of the bottle, said conduit being provided in the glass of the latter.

3. A bottle having a restricted opening in the neck thereof for the formation into drops of liquid poured from the bottle through the restricted opening which serves at the same time to admit air to the bottle, a transverse wall in the neck of said bottle, said restricted opening being formed in said transverse wall, a conduit for the formed drops on the outer surface of said transverse wall, said conduit being in communication with the drop formingledge of said restricted opening in said wal 4. A bottle having a restricted opening in the neck thereof for the formation into dro s of liquid poured from the bottle through restricted opening which serves at the same time to admit air to the bottle, a transverse wall in the neck of said bottle, said restricted opening being formed in said transverse wall, a groove for conducting the formed drops on the outer surface of said transverse wall, said groove being in communication with the drop forming edge of said restricted opening in said well.

5. A bottle having a restricted opening in the neck thereof for the formation into drops of liquid poured from the bottle through the restricted opening which serves at the same time to admit air to the bottle, a transverse wall in the neck of said bottle, said wall being located at some distance from the mouth of said neck, said restricted opening being formed in said transverse wall, a conduit for the formed drops on the outer surface of said transverse Wall, said conduit being in communication with the drop forming edge of said restricted opening in said wall.

6. A bottle having a restricted opening in the neck thereof for the formation into drops of liquid poured from the bottle through the restricted opening which serves at the same time to admit air to the bottle, a transverse wall in the neck of said bottle, said restricted opening being formed in said transverse wall, a conduit for the formed drops on the outer surface of said transverse wall, said conduit being in communication with the drop forming edge of said restricted opening in said Wall, a screw-thread on the outside of said neck, a transverse groove through said screwthread, said transverse groove being arranged adjacent to said conduit in said Wall.

In testimony I have hereunto set my hand.
